CME NEAR-MISS POSSIBLE ON JUNE 5TH: A minor coronal mass ejection (CME) that left the sun on June 1st will pass close to Earth on June 5th, according to NOAA analysts. It might come close enough for a glancing blow. High latitude sky watchers should be alert for auroras when the CME arrives this weekend.
